I all whom it may concern.-

Be it known that I, CHARLES A. I\IILLER, a citizen of the United States,residing at Sturgis, in the county of St. Joseph and State of Michigan,have invented certain new and useful Improvements in Tanks for Water-Closets, of which the following is a specification.

This invention relates to improvements for flushing tanks forwater-closets.

Flushing-tanks for water-closets as ordinarily constructed soon becomechecked or warped or the joints become loosened and pull apart.

It is the main object of this invention to provide an improvedflushing-tank for water-closets which is not liable to become so injuredor damaged, which is simple and economical in structure.

Further objects and objects relating to structural details willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawings, forming a part of thisspecification, in which Figure 1 is a perspective view of my improvedflushing-tank for water-closets. Fig. 2 is a detail transverse sectionalview therethrough. Fig. 3 is a detail vertical sectional view taken on aline corresponding to line 3 3 of Fig. 2 looking in the direction of thelittle arrows at the ends of the section-lines.

In the drawings similar letters of reference refer to similar partsthroughout the several views.

Referring to the drawings, I provide a reservoir-boX which is made up ofthe end walls A and the side or front and rear walls B B, respectively.These walls are suitably secured together, and the front and end wallsare secured to the bottom D. The rear wall B is left out of contact withthe bottom D, leaving a narrow slit or opening b under the same.

l/Vithin the reservoir-box I place a suitable metal water-reservoir It.I provide an outer casing C for the reservoir-box. This casing ispreferably made of a single piece of veneer, which is bent into suitableshape to inclose the front and end walls of the reservoir-box,

leaving an air-space between them and the casing. The-bottom D projectsbeyond the walls of the reservoir-box, and the casingwall C reststhereon, so that it forms a bottom therefor. Angle-shaped strips 0 aresccured to the rear ends of the casing-Wall and are lapped upon the rearends of the end walls A of the reservoiebox. (See Fig. 2.) The tops ofthe reservoir-box and of the easing therefor are made flush, so that thecover D serves as a cover forboth. Thus arranged I secure an inclosedair-space about the ends and front of the reservoir-box. Thereservoir-boX is provided with a pair of upwardlyprojecting dowel-pinsd, adapted to engage suitable holes in the cover D to guide it intoplace and retain it in position. The bottom D and the cover D project atthe rear flush with the angle-strips 0, so that when the structure is inposition on the wall an inclosed air-space is formed between the walland the "reservoir-box. The walls of the reservoir-box are thus entirelysurrounded by air-chambers. WVith the parts thus arranged thecontraction or expansion of the reservoir-box does not affect the outercasing, which may be ornamented or finished as desired without liabilityof its becoming injured. The air-chambers about the walls of thereservoir-box prevent the collection of moisture thereon and theconsequent shrinking and swelling, thereby loosening the joints. It alsodoes away with the necessity for accurately fitting the parts together,as if, as ordinarily constructed, a metal waterreservoir is not a closefit within the box so as to prevent the circulation of air theWater-reservoir will sweat, collecting a large amount of moisture.Should, however, the reservoir-box check or warp from any cause, theappearance of the structure is not affected, as the outer casing isthoroughly protected.

My improved flushing-tank for waterclosets is very economical toproduce, as a great degree of skill is not required in making thereservoir-box and the casing C is easily conformed and put into place.

It is evident from the foregoing that as the parts of my improvedflushing-tank are so well protected the same is very durable.

, I have illustrated and described my improved flushing-tank forwater-closets in detail in the form preferred by me on account of itsstructural simplicity and economy. I am, however, aware that it iscapable of con- IIO siderable variation in structural details withoutdeparting from my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a tank for water-closets, the combination of a reservoir-boxhaving a projecting bottom and an opening beneath its rear wall; asuitable water-reservoir; a casing for said reservoir-box, consisting ofa single pieceof veneer conformed to inclose the front and j end wallsthereof, resting on said projecting bottom; angle-shaped strips engagingthe j rear ends of said casing and lapped upon the rear wall of saidreservoir-box; upwardlyj projecting dowel-pins on said reservoir-box;and a cover common to both said reservoirboX and said casing, havingsuitable holes therein adapted to be engaged by said dowelpins wherebyit is guided into and retained in position, whereby the walls of saidreservoir box are surrounded by air-chambers, for the purpose specified.

2. In a tank for water-closets, the combination of a reservoir-boxhaving a projecting bottom; a suitable water-reservoir; a casing forsaid reservoinbox, consisting of a single piece of veneer conformed toinclose the front and end walls thereof, resting on said projectingbottom; angle-shaped strips en aging the rear ends of said casing andlapped upon the rear wall of said reservoir-box; upwardlyprojectingdowel-pins on said reservoirboX; and a cover common to both saidreservoirbox and said casing, having suitable holes therein adapted tobe engaged by said dowelpins whereby it is guided into and retained inposition, whereby the walls of sa d reservoir. boX are surrounded byair-chambers, for the purpose specified. v

3. In a tank for water-closets, the combination of a reservoir-boxhaving a projecting bottom and an opening beneath its rear wall; asuitable waterreservoir; a casing for said reservoir-box, consisting ofa single piece of veneer conformed to inclose the front and end wallsthereof, resting on said projecting bottom; angle-shaped strips engagingthe rear ends of said casing and lapped upon the rear wall of saidreservoir-box; and a cover common to both said reservoir-box and saidcasin whereby the walls of said reservoir- 1 box are surrounded byair-chambers, for the purpose specified.

4. In a tank for water-closets, the combination of a reservoir-boxhaving a projecting bottom; a suitable water-reservoir; a casing forsaid reservoir-box, consisting of asingle piece of veneer conformed toinclose the front and end walls thereof, resting on said projectingbottom; angle-shaped strips engaging the rear ends of said casing andlapped upon the rear Wall of said reservoir-box; and a cover common toboth said reservoir-box and said casing, whereby the walls of saidreservoirbox are surrounded by air-chambers, for the purpose specified.

5. In a tank for water-closets, the combination of a reservoir-boxhaving a projecting bottom; a suitable water-reservoir; a casing forsaid reservoir-box inclosing the front and end walls thereof, resting onsaid bottom; upwardly-projeting dowel-pins on said reservoir-box; and acover common to both said reservoir-box and said casing, having suitableholes therein adapted to be engaged by said dowel-pins whereby it isguided into and retained in position, whereby the walls of saidreservoir-box are surrounded by airchambers, for the purpose specified.

6. In a tank for water-closets, the combination of a reservoir-boxhaving a projecting bottom; a suitable water-reservoir; a casing vforsaid reservoir-box inclosing the front and end walls thereof, resting onsaid bottom; and a cover common to both said reservoir box and saidcasing whereby the walls of said reservoir-box are surrounded byair-chambers, for the purpose specified.

7. In a tanl for water-closets, the combination of a reservoir-box; asuitable waterreservoir; a casing for said reservoir-box formingair-chambers about the walls thereof, said reservoirboX and said casinghaving a bottom and top common to both, for the purpose specified.

In witness whereof I have hereunto set my hand and seal in the presenceof two witnesses.
